CAR-REPLACER.

Application filed August 26, 1915.

To all whom it may concern:

Be it known that I, LEVI MGENTYRE, a citizen of the United States, residing at Cayuga, in the county of Vermilion and State of Indiana, have invented certain new and useful Improvements in (lar-Replacers, of which the following is a specification.

This invention contemplates an improved car replacer and relates more particularly to improvements in the construction embodied in Patent No. 1,1425%, issued to me June 8, 1915.

The invention has as its primary object to provide a car replacer consisting of a pair of complemental frogs adapted to be placed respectively upon the inside and out-side of a railway track and provided with. means for detachably engaging the rail for bold ing the frogs in a fixed position relative thereto.

The invention has as a further object to provide the frogs with complemental grooves and shoulders for efficiently directing the wheels of'rolling stock onto the railsand'to at the same time provide a very simple construction for effecting this result.

And the invention has as a still furtherobject to so form the frogs that the coacting grooves and ribs thereof will act to gradually direct the wheels of the rolling stock laterally back onto the rails and wherein the frogs will be so formed as to prevent the wheels from slipping or being moved clear over the treads of the rails and becoming again displaced.

Other and incidental objects will appear as the description proceeds and in the draw ings wherein I have illustrated the preferred embodiment 'of the invention and wherein similar reference characters designate corresponding parts throughout the several views.

Serial No. 47,470.

Fig. 5 is a transverse sectional view taken on the line 5 5 of Fig. 4 and looking in the direction of the arrows, this view particularly illustrating the manner in which the frog is provided with handles,

Fig. 6 is a sectional view taken on the line (i-6 of Fig. 1 and particularly showing the contour of the floor of the frog,

Fig. 7 is a fragmentary elevation showing one ofthe dogs employed for locking the frogs in engagement with the ties of the track.

In carrying out my invention, I employ complemental frogs indicated as a whole at A and B, respectively, the frog A being placed upon the outside of the adjacent rail of the track as shown in Figs. 1 and 2 of the drawings, while the frog B is placed upon the inside of the other rail. In the interests of clarity, these frogs will be separately de scribed.

The frog A includes a body portion 10 having a floor 11 which slopes in opposite directions toward the ends of the body portion and is widened midway its ends as particularly shown in Fig. 1. Extendii'ig laterally from the floor, are spaced supporting walls 12 and 13 respectively which are joined at a plurality of points by transversely extending webs let. The wall 12 slopes outwardly at its extremities away from the wall 13 while the wall 13 is straight and is cut away along its lower edge to rest upon the base flange of the rail as particu larly shown in Fig. 2 of the drawings, as are also the lower forward edges of the webs 14. Formed on the lower edge of the rear wall 12 at longitudinally spaced points, are spurs 15 adapted to engage the ties of the road bed.

The outer face of the wall 12, at a point substantially midway its ends, is cut away to provide a substantially circular recess or seat in which is mounted to swing an anchoring hook 16 as shown in Fig. 7 of the drawings. The hook 16 is pivotally supported upon a pin 17 and adapted to engage the ties of the road bed as shown in Fig. 7 to prevent any creeping of the frogs. Either end of the hook is adapted to be engaged with the tie as will be readily seen. Arranged to cooperate with the hook are pivotally mounted buttons 18 adapted to en gage opposite ends of the hook for holding it in working position.

The widened portion of the floor 11 is exll AL tended laterally and is provided with a terminal flange 19 to define a hook 20 adapted to engage over a rail as particularly shown in Fig. 2 of the drawings. Pivoted in the flange 19 is a cam lever 21 adapted to engage the web of the rail for holding the frog in a stationary position relative to the rail.

It will be noted that the hook 20 projects inwardly over the tread of the rail and at its outer extremity, is provided with a longitudinally extending groove 22 adapted to receive the flange of a car wheel, the said groove being located upon the inner side of the adjacent rail. Formed in the floor 11, is a similar groove 23 which extends from end to end of the floor. Each extremity of the groove 23 is arranged substantially midway the transverse width of the adjacent end of the floor and thence curves gradually inwardly as its approaches the summit of the floor to open into the groove 22. The body of the frog A thus described, may

be formed as a single casting or may, if

desired, be constructed from sheet metal or any other suitable material, it being observed that the hook 16, the abutments 18 and the cam lever 21 may be easily attached.

The frog B includes a body portion 24 similar in general outline to the body portion of the frog A. The body portion 24L includes a floor 25 having depending supporting walls 26 and 2-7 respectively. The supporting wall 26 is straight while the wall 27 diverges away from the wall 26 fro-m a point substantially midway the ends of the floor toward the extremities of the said wall, it being observed that the floor 25 is gradually widened toward its extremities and slopes in opposite directions from a point substantially midway the ends thereof.

Connecting the walls 26 and 27 at longitudinally spaced points are transversely extending webs 28, the forward lower edges of which are cut away to seat upon the base flange of the rail as particularly shown in Fig. 2 of the drawings. Formed on the lower edge of the wall 27 at spaced points, are spurs 29 adapted to engage the ties or a road bed while the floor 25 at its extremities'and upon the under side thereof is provided with similar spurs 30. To facilitate the handling of the frogs, the terminal webs of the webs 28 at the extremities of the frogs are provided each with an opening 31. and thus. in effect, form handles. In this connection, it may be stated that the terminal. webs of the webs 14 of the frog A are formed with handles in a similar manner.

The outer face of the wall 27 at a point substantially midway the ends of the Said wall is recessed toreceive an anchoring 5 book 16, previously described in connection with the frog A, which is pivotally mounted upon a pin 17 and is adapted to be held in working position by buttons 18.

The floor 25, at a point substantially midway its ends is extended laterally and is provided with a terminal flange 32 to define a hook 33 adapted to engage over the tread of a rail as shown in Fig. 2 of the drawings. Pivotally mounted in the flange 32 is a cam lever 3 1 similar to the cam lever 21 of the fro A and adapted. to engage the web of a rail for holding the frog in stationary position relative thereto. It will be observed that the cam lever, the spurs and the anchoring hook of each frog are adapted to coact to prevent any creeping of the frogs relative to the rails.

Formed on the upper side of the hook 33 is a longitudinally curved rib 35 which extends longitudinally of the hook and the convex upper face of which merges gradually into the surface of the upper side of the hook at the extremities of the rib.

As particularlyseen in Figs. 1 and 2 of the drawings, the inner vertical wall of the rib 35 is arranged in a plane with the outer face of the wall 26 of the frog, the saidrib, when the frog is in position adjacent the rail, being disposed immediately over the tread of the rail with the said vertical wall in alinement with the inner edge of the tread.

Formed upon the outer edge of the floor 25 is an upstanding rib 36 which extends from end to end of the floor. The rib 36 adjacent its extremities provides shoulders 37 inclining gradually in the direction of the rib 3F and is thickened midway its ends, as particularly shown in Fig. 3 of the drawings, to provide shoulders 38 inclining acutely toward the rib 35. and intersecting at a point substantially midway the ends of the said rib. Formed on the upper face of the floor 25 and arranged adjacent the rib 36 is a longitudinally extending groove 39 having the same general longitudinal curvature as the said rib. The floor 25 is provided with a second longitudinally extending groove 40 which is arranged adjacent the inner side of the rib 35 and opens at its ex tremities through the adjacent edge of the floor contiguous to the ends of the said rib, as more particularly shown in Fig. 3 of the drawing. The grooves 39 and 40 communicate at the summit of the floor 25. As in the case of the frog A, the body of the frog B may be formed as a single casting or may be constructed of sheet metal or any other suitable material.

It will now be seen that the flanges of a pair of wheels moving upward upon contiguous ends of the frogs will be received one within the groove 23 of the frog A or the other within the groove 39 of the frog T when the Wheels will be directed laterally eashes upon the frogs. Should one of the flanges engage within the groove 39 of the frogB, the adjacent shoulder 37 of the said frog will, at the same time, engage against the inner side of the wheel upon the said frog to direct the wheels laterally.

As will be seen, the initial lateral movement imparted to the wheels as they ascend upon the frogs will be gradual owing to the gradual inclination of the grooves at their outer extremities and the said shoulder toward the rails, but, after the wheels have thus been started upward upon the frogs and the inertia of the wheels overcome, the lateral movement imparted to the wheels will become more pronounced as they approach the summits of the frogs, due to the increased curvature of the grooves toward the rails. As the wheel upon the frog B leaves the shoulder 87 at the adjacent end of the frog, the contiguous shoulder 38 engages against the inner side of the wheel to urge or direct the pair of wheels laterally upon the frogs. Upon reaching the summits of the frogs, the flange of one wheel will move into the groove 22 of the frog A while the flange of the other wheel will move into the groove 40 of the frog B with the tread of the said last mentioned wheel engaging the rib 35.

Particular attention is now directed to the fact that the vertical inner shoulder of the rib 35 is adapted to engage the flange of the wheel resting upon the said rib as particularly shown in Fig. 2 of the drawings, to prevent the wheels from being shifted entirely over the treads of the rails, this being a highly important feature. In any instance where the wheels are rolled upwardly upon the frogs with considerable momentum, the tendency of the wheels upon reaching the summits of the frogs is to jump clear over the rails, and it will be noted that the presence of the rib 35 in the present construction will effectually overcome any such possibility.

Upon reaching the summits of the frogs, the groove 22 of the frog A and the groove 40 of the frog B will then engage the flanges of the wheels to direct the wheels onto the rails, the groove 40, at its extremities opening through the adjacent side edge of the floor 25 of the frog B as previously stated, for this purpose. It will therefore be seen that I provide a very simple and efficient construction and it will, of course, be understood, that the relative position of the frogs with regard to the rails may, if desired, be reversed.

It will also be seen that I provide an arrangement wherein the wheels of rolling stock may, without any sudden jars or jerks, be gradually directed onto the track, this being one of the salient features of the present improvements distinguishing the inven- (in mile" tion from the construction disclosed in my former patent referred to. At the same time, the coacting frogs, in the present instance, are formed to more elliciently cooperate with eachother and to more el'lectually coact with the wheels of rolling stock passing thereover for positively directing the said wheels onto the rails without likelihood of shifting the wheels entirely over the rails to become again displaced. Furthermore, in the present replacer, the construction of the frogs is materially simplified and the frogs lightened in weight so that the replacer may be more easily manipulated.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A car replacer including a frog having a body portion provided with a floor sloping toward opposite extremities of the frog, the frog being extended laterally and provided with a depending flange defining a rail engaging hook, a longitudinally curved upstanding rib carried by the hook and adapted to receive the tread of a wheel, and a longitudinally extending rib carried by the floor and provided at each extremity thereof with angularly disposed shoulders sloping toward the said first mentioned rib, there being a wheel flange receiving groove formed in the floor at the base of said rib and having angularly disposed portions corresponding to the said shoulders and adapted to coact therewith.

2. A car replacer including a frog having a body portion provided with a floor sloping toward opposite extremities of the frog, a rail engaging hook carried by the frog, there being a longitudinally extending wheel flange receiving groove formed in the floor and curving intermediate its ends toward the hook, an upstanding rib carried by the hook and adapted to receive the tread of a wheel, and a longitudinally extending upstanding rib formed on the floor upon the side of said groove. remote from the hook and providing at each extremity thereof, angularly dis posed shoulders sloping toward said first mentioned rib.

3. A car replacer including a frog having a body portion provided with a floor sloping toward opposite extremities of the frog, a rail engaging hook carried by the body portion, there being an upstanding longitudinally curved rib formed on the upper side of the hook with the inner side of said rib arranged flush with the adjacent side of the frog, the said rib being adapted to receive the tread of a wheel, there being a longitudinally extending wheel flange receiving groove formed in the floor adjacent said rib and opening through the continguous side edge of the floor at the extremities of the rib, and an upstanding rib formed on the outer edge of the floor and extending longitudinally thereof, said last mentioned rib at its extremities providing angularly disposed shoulders sloping toward the said first mentioned rib, there being a longitudinally extending wheel flange receiving groove formed in the floor adjacent said last mentioned rib and curving longitudinally intermediate its ends to communicate with said first mentioned groove.

l. A car replacer including compleinental frogs each having a body portion provided with a rail engaging hook and formed with a longitudinally curved floor, the hook of one of said frogs being formed with a longitudinally extending wheel flange receiving groove and the hook of the other of said frogs being formed with an upstanding wheel flange engaging stop shoulder adapted to cooperate with said groove with the hooks adapted to fit over the rails of a track for holding the said frogs in operative position relative thereto, and a rib carried by the floor of said last mentioned frog with the said rib adapted to engage the flange of one of a pair of car wheels for directing the car wheels laterally over the floors of said frogs to a position with the other Wheel of said pair engaging in the said groove with the flange of said first mentioned wheel engaging the said stop shoulder for limiting the wheels in their lateral movement.

In testimony whereof I affix my signature;
